DELIVERY CHUTE FOB USE LVITH CUTTING- DIES.

. application filed August 25, 1922. Serial No. 5 4,177.

for-use With cutting dies, mymoreparticular purpose being to facilitate the delivery of the articles cut out by the dies in such min or becoming unduly crowded.

M3 invention further contemplates the ar iangement of the delivery mechanism so that the cutting operation of thedies, and

the delivery of the finished article out there 'by, require only arminimum of space.

In addition my invention comprehends an arrangement of the delivery mechanism so that practically all portions of the latter are accessible to the operator at all times, and even while the mechanism is in operation.

More particularly stated, I seek to produce a delivery 'mechanism especially adapted for use in connection with 'apair ofv cutting dies of the type used for making-cardboard fans and similar articles the mechanism being so distributed and arranged in position thatthe cutting dies may- 'work continuously, and the articles cut out by the dies are to all, intents and purposes automatically assembled and delivered from the cutting'dies, the. power for this purpose being supplied by the normal worlc ing or cuttingmovement of one of the die members relatively to the other.

Reference is made to the accompanying drawingforming a part of this specification, and in which like reference characters indicate lke parts throughout the several figures,

Figure 1 is asubstantially central vertical section through a pair of cutting dies equipped with my device.

Figure 2 is a sect'on on; the line Zr- 2" of Figure 1, looking intheidirection indicated by the arrows. I

Figure 3 is a section on the line 33 of Figure 1, looking in the direction indicated by the arrows. a 4

1 A strip of, cardboard is shown at 4, and

is used in making the body portion of the fans, to be cut, as hereinafter described,

The cardboard strip 1 is preferably of great length, and is fed endwise in the manner well known in this art. This cardboard strip carries a number "of substantially V- shaped handle membersb and 6, arranged in pairs, the membersof each pair bemglocated upon opposite faces of the cardboard strip 4: and adhering to the cardboard strip a by aid of an adhesive. For purposes of my invention, therefore, the cardboard strip 1 ma be considered as a continuous strip having the form indicated in Figures 1 and 2, and fed continuously endwise, with a. step by step movement, in the manner well undertood in this art. 7 H

A portion of thestrip 4 to be cut out by the dies is shownat 7, and at 8 is shown a similar portion as it is cut from the strip and thus converted into a fan.

The two members of the cuttingdie are shown at 9 and 10, and'constitute'the positiveand negative members of the die. The lower. diemember 10 is the negative member of the die and is secured upon a table, shown fragmentarily at 11 and provided with an opening 12, through which the fin-v ished fans pass downwardly, as indicated in Figure 1. .The lower die member 10 carries a number of guide pins 13 which extend upwardly, through holes in the die member 9. The upper die member 9 is mounted to slide vertically upon the guide pins 13, and is thus always strictly parallel with thelower die member 10.

The upper die member 9 is provided with a cutting edge14c, and the lower die member 10' is provided with a mating cutting edge 15. These cutting edges are so formed a that in severing the portion 7 from' the strip 4,,such portion is given the form' indicated at 8 in Figure :2; orin other words the dies are properly formed to give the required shape to thefinished fan.

For actuating the upper die member 9 it is provided with a pin 16, and journaled upon this pin is a link 17 connected with and operated by an eccentric 18, this eccentric being mounted upon a revoluble shaft 19, through which power is supplied. Thus theupper die member 9 is caused to reciprocate relatively to the die member 10, so as to continuously cut outfans 8, one ata time,

By means of bolts 20 the die member 10 is held rigidly in position, so that the die mechanism as a unit is fixed relatively to thesupporting'table 11.

7 Each fan 8, after being severed from the cardboard strip at as above described, has the form shown in Figure 3. It is provided with a hole 22,'to be used by the operator as a thumb hole, and is further provided with a pair of concave edges 23 having but little curvature, and a pair of other conof rails 26.

Therails 25 and 26 arein this instance each circular in cross section, the rails 26 each being of smaller diameter than either of the rails 25, and located a little lower than the latter, but in close proximity thereto. The rails 25 and 96 are so proportimied and arranged that each tan 8 supported by them as indicated in i .re rests upon them in the manner shown, the concave edges 23 resting upon the rails 25 and the concave edges Qel resting upon the rails 26. Thus each fan has a good bez'n'ing upon the rails, and is supported quite lirnily thereupon, by its own weight.

The rails 25 are supported by pins 27, extending through sidcboards 28 and having portions 29, threaded and of reduced diameter, which extend through the sideboards and are engaged by nuts 30, as shown more particularly in Figure 3. The rails 26 are supported upon pins 3i, which extend laterally inward from the sideboards.

The Sideboards 2S and the various parts carried thereby are supported upon legs 32 and 33, the latter being secured to a floor 34 or analogous supporting surface by means of bolts 35. i

I provide a pair oil. brackets one of which is shown at 36, for sup iort ng the portions oil. the side boards 28 in immediate proxinr ity to the die number 10.

The guide rails 25 and E36 and parts iniinediatcly associated. therewith collectively constitute a chute for supporting and guiding the fans 8, as the latter are cut one at a time as above described and thus 'tcd into the chute in a manner practically automatic. It will be noted that in consequence of the location oi. the cardboard handle members 5 and (3 carried by and forming a part of each fan, the :t'an as a whole is practically rendered thicker at one point than at another. That is to say, broadly speaking, the portion of the tan serving as a handle and shown at the bottom of Figure 3 is considerably thicker than the upper portion of the tan according to this figure. Such being the case, when a number of the fans are crowded together as shown in Fig ure 1, so that the relative thicknesses of the fans is in a sense cumulative, the entire form approximating that of a paraljiola, and

the body of tune as a unithas at any par ticular moment the form oi a column, bent substantially into a form corres-iponding to the path of travel of each tan.

It will be noted that the guide rails and 26 are each substantially straight in the portion to the right .thercoi according to Figure 1. In other words the guide rails are straight in that portion of the chute from which the fans are actually removed by hand. liy this arrangement the upper or blade portions of the fans are spaced apart slightly, as indicated in Figure 2, so that the operator can readily sl plns lingers 111 between any two tans which are consecutire and located near the end of the column. By doing this with one hand so as to sepa:

rate a bunch of fans from the generalcolulnn, and by placing his other hand under neath the bunch of fans thus separated, he simply slides or lifts the bunch oil the guide rails and thus effects the removal 01 the fans.

lit will be noted froinl igure .2 that the general axis of each fan as cut from the cardboard step el is oblique relatively to the length of the cardboard strip. This is for the purpose of avoiding waste in cutting the cardboard. Therefore I so ar ange the .various parts of my device that the chute, as a whole, occupies a. general vertical plane which is oblique to the length of the strip l and to the general direction 01' travel thereof. This arrangement renders the movement of each tan comparatively simple, and causes the column of finished fans to leave the cutting dies in such direction of travel that, seen from above, the column of fans is oblique to the general direction of the length of the strip a. By this arrangement the column of fans occupies such position relatively to the cutting dies as to facilitate access to the cuttingdics and parts innncdiately associated therewith. Thus the operator can stand quite close to the cutting dies and directly in linowith the length of the strip l and with the direction of, travel thereof, for the purpose of inspecting the cutting dies, and removing shreds of cardboard formed by the cutting of the fans. In other words, p ctically speakingfthe chute guides the column of fans out under a corner of the table, so to speak, thus rentherein without departing from my invention, the scope of-which is commensurate with my claims. r

I claim I 1. The combination, with a pair of cutting dies one of which is movable and'the other stationary, of a chute connected with the stationary die and comprising a number of guide rails each having the form of a rod, said rails being arranged in pairs, the rails of each pair being spaced apart the rails of one pair being spaced further apart than the rails of another pain all of said rails being together so positioned relatively to the stationary die as to receive and deliver the articles cut by the dies.

2. In a device of the character described the combination, with a stationary die'provided with an'opening and a movable die provided with a cutting portion mating said opening and adapted to extend thereinto,

of meansfor guiding between said dies a longitudinal strip of stock material traveling step by step in the direction of its length. a chute communicating with said opening "and arranged to receive therefrom the articles cut by the dies said chute being curved in a substantially vertical plane for the purpose of delivering said articles to a predetermined point, saidvertical plane of said chute extending obliquely to the direction of travel of said strip of stock material.

3. In 'a device of the character described the combination, with a stationary cutting die provided with an opening and a movable cutting die provided with a cutting portion mating said opening and adapted to extend thereinto, ofmeans for feeding a strip of stock material in the direction of its own length to said dies along a straight path, and a chute communicating with said opening and arranged to receive therefrom the articles cut out by the dies. said chute extending in a plane oblique to thelength of said strip of stock material.
